This 'ible is an example of what can you do with transparent resin, so the following instructions can be taken for other ideas. The resin used is Transparent Polyester. I bought it on this store , very cheap by the way.
Step 1: Safety First
Resin can become an hazardous issue if you don't take the correspondent precautions. There are required some protections:
- Latex or nitrile gloves.
- A Mask for the fumes
- Acetone (is the best product for clean polyester resin).
Step 2: Tools and Materials
· Wet sandpaper 120
· Wet sandpaper 360
· Wet sandpaper 1000
- Sander (optional but recommended)
- A graduated cylinder (to measure the resin)
- syringe (to measure the catalyst)
- A stick
- Solder iron
- Hot melt glue gun
- Polish paste
- Polyester Transparent Resin
- A object to sink (in this case an lens aperture)
- A mold (I used a tetra brick pack, but I recommend crystal or plastic, you wont have to sand with them)
- 4 LED's
- Plug conector
- 12V transformer
Step 3: Dissasemble the lens and aperture
Take apart the aperture and disassemble it as well.
Step 4: Make the mold
My mold was made on tetra brick, because I haven't anything better, but plastic and crystal containers are a better option. Silicone is the best option, but is a waste of money if you'll only use it one time.
I made two pieces. One for the base, which is illuminated by four LED's, and other for the aperture piece.
Step 5: Make the base light
Step 6: Prepare the resin
Catalyst quantity may vary depending on the temperature of the environment, but is always between 5 and 2% of the volume of the resin.
After mix them in a recipient, stir it with a stick drawing an eight. That will erase most of the bubbles that can appear.
Resin dries relatively quick(around 5 - 10 min.), so you'd better control your time.
Don't make a big amount of resin for this project in a time, because it will be poured by layers.
Step 7: Pouring the Resin
Right after mix the resin with the catalyst, pour it into the mold. Put the first aperture piece with care then.
To create the "exploded" effect, I put the resin by layers, each layer for one part of the aperture.
Wait around 30 minutes so as to let the resin dry well and prepare more resin mix for the next layer.
After make all the layers, let it dry 12 hour's.
Step 8: Extract the Resin Piece
Step 9: Sand the piece
Afterwards, sand the piece first with the 120 sandpaper, then with the 360, and finish with the 1000.
I sanded the base only with the 120 and 360 sandpaper, giving it a semi-transparent look.
This is the hardest step so far. I spend at least 4 hour's sanding, just because my mold was very irregular, so take care about that.
Step 10: Polish the Piece
Step 11: Finished!
So this is the result of the hard work! I hope you enjoy this instructable.
